The same day that a Washington Post-ABC News poll showed public support for President Bush’s energy policy at 37 percent, Vice President Dick Cheney held his first serious meeting with environmental groups. During the session yesterday, leaders from four green groups asked the Bush administration to work to boost fuel-economy standards to 40 miles per gallon for cars and SUVs; require electricity suppliers to produce 20 percent of their power from renewable sources by 2020; and set limits on carbon dioxide emissions from power plants. Cheney was present for 20 minutes of the hour-and-a-half-long meeting.
